Bug: npm resolvers default export not working as expected

[apollo79]

Using the following code:

import Ajv from "npm:ajv@8.11.0";

const ajv = new Ajv();

An error occurs:

This expression is not constructable.
Type 'typeof import("file:///<user>/deno/npm/registry.npmjs.org/ajv/8.11.0/dist/ajv")' has no construct signatures. deno-ts(2351)

Strangely enough Ajv has a property default which is the default export, so the following works:

import Ajv from "npm:ajv@8.11.0";

const ajv = new Ajv.default();

The same happens with ajv-formats:
This throws:

import Ajv from "npm:ajv";
import addFormats from "npm:ajv-formats";

const ajv = new Ajv.default();

addFormats.default(ajv);

But this works:

import Ajv from "npm:ajv";
import addFormats from "npm:ajv-formats";

const ajv = new Ajv.default();

addFormats.default(ajv);

The same thing occurs with Node ESM importing this package, so this is not an issue in Deno. See here: ajv-validator/ajv#2132
